[Crossover] I Heard You Bullied My Kid?

A legend has spread through the demon realm: If you offend Lord Ibaraki Doji, at worst you'll be crushed to smithereens. If you offend Lady Ibaraki Nanako... Get ready to be beaten half to death by Lady Nanako, then crushed to smithereens by Lord Ibaraki Doji. Nanako: Nonsense. I'm not that violent. I'll only beat you until you're black and blue at most :) After all, I'm not some kind of demon. Also known as: The Path to Becoming the Demon King for a Short-Tempered Girl (or Young Woman?) (?) Warnings: Since this involves a young Ibaraki, there will probably be some OOC. Whatever, I make the rules for my Ibaraki baby. Timeline and logic are dead, thanks. Theme:
